Checked RX. There are 3 or 4 H scenes per girl, most of them with 3 CGs, so there's quite a bit of H content. They're mostly in the obvious places, but some are also in the epilogues, somewhat of a pet peeve of mine (for obvious reasons Himeno is a major offender here).
Personally I was more interested in the DCII scenario, which delivered in the nostalgia aspect at least. But that's all there's new. In raw text the 1.3 patch had added more content (and it seems the rhythm mini game is no longer there). DCIIIPC this ain't (not that I was expecting that).
